Question

What is mDFC?

45°
80°
125°
135°

Answer 1

I think the answer is 80 because it is bigger than 45 but smaller than 125 so then it couldn't be 135 either so you have 80.

Answer 2

Option B is correct .i.e, m∠DFC is 80°

Explanation:

We are given measure of ∠ BFC = 45° and measure of ∠AFE = 125°

We have to find measure of ∠DFC

From Figure,

Line BE intersects with line AD at point F.

we know that vertically opposite angles are equal

So, we get

∠BFD = ∠AFE

∠BFC + ∠CFD = ∠AFE

45° + ∠CFD = 125°

∠CFD = 125° - 45°

∠CFD = 80°

Therefore, Option B is correct .i.e, m∠DFC is 80°
